摘　　要：野香优2998是一个感光型三系优质高产杂交水稻新组合,2013年引入琼稻作区作多点试种,2015年通过,审定号为(琼)审稻2015008号。在琼种植,野香优2998表现出株型集散适中,叶稍、叶片绿色适中,后期熟色好,适应性广,抗性好,高产稳产,米质优,口感适中等特点。野香优2998高产栽培技术为:早造在1—3月上中旬播种,播后培育壮秧,适时移栽秧龄3.5~5.0片叶;抛栽600~675片于561孔的塑料秧盘,16.70万~17.02万蔸/hm^(2);机械插秧密度为12.57万~12.60万蔸/hm^(2),手插秧以18.5万~19.1万蔸/hm^(2)为宜;移栽时重施基肥,插后追施化肥;科学控制肥水,防治水稻病虫害。Yexiangyou 2998 is a new photosensitive three-line hybrid rice combination with good quality and high yield. It was introduced into Qiongdao rice-growing area in 2013 and adopted as Qiongdao No.2015008 in 2015. Yexiangyou 2998 had the characteristics of moderate plant type, slightly leaf, moderate green leaf, late mature color, wide adaptability, good resistance,high and stable yield, good quality and moderate taste. The high-yield cultivation techniques of Yexiangyou 2998 were as follows:Sowing in the first ten days of January to mid-march, cultivating strong seedlings after sowing, transplanting 3.5-5.0 leaves at the right time, throwing 600-675 561-hole plastic seedling trays,(16.70-17.02)×10^(4) plant·hm^(-2);The density of mechanical transplanting seedling is(12.57-12.60)×10^(4) plant·hm^(-2), the manual transplanting seedling is(18.5-19.1)×10^(4) plant·hm^(-2), reapplying base fertilizer when transplanting, applying chemical fertilizer after transplanting, scientifically controlling fertilizer and water,preventing and controlling rice diseases and insect pests.
